Abstract

Hibernom is a rather rare benign tumour of younger adults. It is usually located in the interscapular region, in the thigh, the axilla, the head and the neck.

It is of lobular structure, well demarcated, of brown colour in the section. It consists of big polygonal cells with the small nucleus in the middle and multivacuolar bulky, granular, light or eosinophilic cytoplasma.

The normal mature adipocytes are often component (sometimes also myxoid stroma or spindle-shaped cell components are found).
